Community-powered conservation for Hawaiʻi
FeralMap provides an easy and effective way for the community to report feral and invasive animal sightings across Hawaiʻi. By making it simple to document and share observations, we empower residents, visitors, and conservation professionals to contribute to protecting Hawaiʻi's unique ecosystems.
FeralMap is the next evolution of CatMap (hawaiicats.org), the pioneering community mapping tool developed by Nene.org. Building on CatMap's success in tracking feral cat populations, FeralMap expands the platform to cover a comprehensive range of invasive species threatening Hawaiʻi's native ecosystems.
What started as a focused effort to understand feral cat distribution has grown into a multi-species reporting system that helps track pigs, goats, mongoose, axis deer, coqui frogs, little fire ants, and many other invasive animals across the islands.
Invasive species are one of the greatest threats to Hawaiʻi's native wildlife and ecosystems. From feral pigs destroying native forests to mongoose threatening ground-nesting birds, these animals cause significant ecological and economic damage.
Community observations are crucial for:
FeralMap is committed to transparency and open data. All community-submitted reports are made publicly available (with privacy protections where needed) to benefit researchers, policymakers, conservation organizations, and the public.
Our data is shared under a Creative Commons license, ensuring it can be used to inform conservation strategies, scientific research, and public policy decisions that protect Hawaiʻi's natural heritage.
FeralMap is developed and maintained by Nene.org, a conservation technology nonprofit dedicated to protecting Hawaiʻi's native species and ecosystems. We believe that empowering communities with the right tools can make a real difference in conservation outcomes.
Every report makes a difference. Whether you spot a feral cat in your neighborhood, mongoose on a trail, or pigs in the forest, your observations help build a comprehensive picture of invasive species across Hawaiʻi.
